Two figures showing the trends in the average volume of small plankton (tiny, often microscopic creatures floating in the water) collected in the ocean in CalCOFI net samples taken only at sites in the Channel Islands National Marine Sanctuary region (top) and all sites over the Southern California Shelf (bottom) each spring from 1978-2015. Click the map tab to compare the two sampling regions. Figure credit: A. Thompson/NOAA; Ben Best/EcoQuants.
A map showing the locations of spring season net samples by CalCOFI for use in analyses of abundance and trends in pelagic resources. Channel Islands National Marine Sanctuary region (red) includes CalCOFI stations inside and adjacent to CINMS; and Southern California Shelf (yellow) includes all CalCOFI stations over the shelf.
